Determining Location

Mapping Pre-Assessment1. Which is a measure of how far East or West you are traveling? Latitude B. Longitude C. Attitude D. Altitude

2. At 180 longitude, this imaginary line separates one day from another. Prime Meridian B. International Date Line C. Arctic Circle D. Equator

A. 38 NB. 75 WC. 38 WD. 75 N

What are the coordinates for San Francisco?What city is found at approximately 39N, 106W?

Mr. Fetchs Earth Science ClassroomWhy are we Learning about Latitude and Longitude?How could you describe the exact location of a dot on a basketball? It would be just as hard to describe a position on earth without some sort of grid system to give you an exact location.

This grid system is called latitude and longitude.

Latitude and LongitudeLatitude imaginary lines which run east and west BUT measure degrees north or south of the equator0 latitude is the EquatorThese lines never cross

Latitude and LongitudeLongitude imaginary lines that run from North to South Pole but measure degrees east or west of the Prime Meridian0 longitude is the Prime MeridianThese lines cross at the north and south pole

International Date Line - 180 longitude line It separates two consecutive calendar days Note: left of line is one day ahead of right side

Northern HemisphereSouthern HemisphereWestern HemisphereEastern Hemisphere

How to Use It:When saying or writing your location on a map you always:1. Latitude (number, degrees, N or S)2. Longitude (number, degrees, E or W)The coordinates for Miami, FL (see arrow) would be:

25N, 80W

ExampleCharlotte, NC is located at 35 N, 80 W

What would be the latitude and longitude for the arrow pointing at the border between California and Nevada?

It should be: 40N, 120W

OK, now lets do a couple more practice problems. Open your book to pg. 745 and write the answers in your notes:

Location at 40N, 105 WLocation at 47 N, 87 WWrite the approximate latitude and longitude for: New York, NYHawaii (Big Island)

0 Longitude is the Prime Meridian

O Latitude is the Equator

Latitude & Climate

As you increase in Latitude the temperature decreases

Other Important Lines of Latitude What is important about these imaginary lines?
